kconfig_lint: Fix checks when running in taint mode
The builders run perl scripts in taint mode, and some of the checks
that the kconfig lint script were running were tainted, causing
the script to terminate early when running on the servers.
This checks to see if taint mode is enabled, and untaints the path
if it is. All exernal tools (git & grep) must be in /bin or /usr/bin.
This also removes the check for unused kconfig files if taint mode
is enabled.
